For an (yet) unknown reason the memory consumption increases VERY rapidly. So be aware of this fact when testing.

The memory problem occurs in the itk::NumericFileNameWriter called inside of

template < typename TPixel, unsigned int VImageDimension >
void _mitkItkPictureWrite

at this point:

line 53: writer->SetFileNames(numericFileNameWriter->GetFileNames());

The image passed to the _mitkItkPictureWrite method is correctly initialized, i.e. the Region.Size and Region.Index have both valid entries.

Change request written. Requesting core modification flag.
